Very interesting take on what is normally very long-form story telling, by condensing in down to less than 2 minutes they successfully keep only what is absolutely essential to the heart of the series. It still feels a bit hollow, like a PV for the eventual full length anime adaptation, though at the time I don't believe any plans for such were under way. It feels like one of those fan animations you might on youtube celebrating a series rather than an official adaptation. Still, it's very flashy and cool looking which I guess is about as much praise as can be given any shounenbattle anime, so 7/10
